May 2018: our precious eyesight



Our precious eyesight

We don’t normally realize how precious our eyes are, until we get trouble. Short sight, far sight, those are easily dealt with. But what about cataracts, glaucoma, and the feared macular degeneration?
Every so often, another piece appears in the papers about how scientists have
invented a clever way to deal with one or another of these. But even so, and till some of these miracle cures have become mainstream, prevention is still best. 
There are lots of things we can do for ourselves. Good food is always a very important one, which also happens to improve our health in other respects.

DIET
To prevent yourself from getting eye problems, or to alleviate them once you’ve got trouble, it is important to include the following in your diet. 
Lutein and zeaxanthin: in eggs (free range), coloured fruit, leafy green, spinach, kale, collard greens, cos, broccoli, sweetcorn, peas, Brussels sprouts, pumpkins, orange peppers, pistachio nuts, grapes.
Carotenoids are plant pigments responsible for bright red, yellow, orange and dark green hues: in for instance carrots, spinach, kale, Brussels sprouts, cabbage, sweet potatoes, tomatoes, red capsicums and oranges.
Vitamin A/beta-carotene: liver, egg; fruits/veg (carrots, pumpkin, squashes, spinach, kale, tomatoes).
It's important to combine lutein, carotenoids and vitamin A with fat like butter or olive oil, so our bodies can absorb the benefits.
Zinc: oysters, shellfish in general, meat/poultry, beans/peas, nuts/seeds, egg yolks, whole grains, cheese. Veg(etari)ans: see [1].
Vitamin C: we all know where they are: in fruit and veg, especially when eaten raw. 
Vitamin E: in seeds/(pea)nuts, dark leafy greens like spinach, broccoli, plant oils, (shell)fish, pumpkin, avocado. 
B-vitamins: B2 deficiency can lead to dimmed vision and red, itchy, burning eyes. In meat, cheese, almonds, mushrooms, spinach, marmite/brewer’s yeast, eggs, milk. This vitamin is damaged by light.
Vitamin B6 can prevent macular degeneration when taken with B12. It also improves absorption of magnesium, which helps production of tears. In seeds, nuts/seeds, fish, poultry/meat, dried fruit, capsicum, spinach, broccoli, marmite/brewer’s yeast, whole grains, beans/peas, potatoes in their skins. 
Vitamin B12 lessens our chance of getting macular degeneration, when taken with B6. It also prevents glaucoma. In (shell)fish, liver, beef/poultry, marmite/brewer’s yeast, milk/yoghurt and eggs.
Omega 3: in oily fish (sardines, mackerel, herring), walnuts, flax seed/oil and egg yolks. Brussels, kale, spinach, pumpkin, broccoli and watercress also have some, but in a less useful form.
See also [2].

ALCOHOL CONSUMPTION doesn’t help our eyesight at all. It drains our stores of critical vitamins and nutrients, like the above mentioned vitamin A and zinc. It also depletes supplies of B-complex vitamins: this can harm the liver [3], which converts beta-carotene into this vitamin A. Dry or red eyes are only a minor effect [6]. Much worse is that drinking alcohol increases the risk of cataracts, glaucoma and age-related macular degeneration. See [4].

MACULAR DEGENERATION develops when the part of the eye responsible for central vision stops functioning properly. Reading becomes difficult, colours less vibrant and faces are hard to recognise. It is the leading cause of severe, irreversible vision loss in people over 60, which is why they often speak of AMD, age-related macular degeneration.
There are two forms, the wet and the dry, the latter being most common. There is no treatment for the dry form, but a lot can be done with the proper food and supplements. The wet form cannot be cured, only slowed down, mainly with injections [5]

BLUE LIGHT
Very important, and not commonly known, is the damage done by so-called blue light. This is light with wavelengths shorter than 480 nanometer. It is harmful because it can penetrate all the way to the back of the eye, bypassing the eye’s natural filters. Blue light is not new, but the amount of exposure we get, through digital devices and energy-saving lights has grown enormously. Artificial sources include smart phones, tablets, computers, Mp3 players and TV’s; also CFL’s, LEDs or halogen, the so-called energy-efficient lightbulbs. The effects of these are cumulative, and macular degeneration can be the result [6].
Fortunately we can protect ourselves by wearing so-called blue-blockers, glasses (often fit-over ones) which block the harmful rays [7].
PS It’s interesting to read what we are supposed to go through when one of those supposedly eco-friendly bulbs breaks - see [8]!

CATARACTS
Risk factors for cataracts are: a history of the condition in the family; smoking; over-exposure to UV rays; regularly drinking too much alcohol; diabetes; eye surgery; corticosteroid medication or a high intake of refined sugar.
When in the first stages of cataract formation, it is relatively easy to slow or stop the process. You can of course wait till they get worse, but a cataract operation, though common, is still an operation. And while most patients get good results, a small percentage are left worse off. And did you know that up to 3% of those who have had cataract surgery will in future develop a detached retina?
If you decide to try and do something yourself to protect your eyesight, remember that this will benefit the rest of your body as well.
So what can you do at this moment?
In the first place, follow the above advise about food. Lutein and zeaxanthin; vitamin B1, B2, C and vitamin E are excellent. Alpha lipoic acid is a powerful anti-oxidant - in organ meats and spinach. Supplements never work so well, and have their drawbacks. Glutathione, another strong antioxidant, is produced in our body. Production is boosted by eating: asparagus, broccoli, avocado, spinach, garlic, grapefruit, squash, potatoes, courgettes, watermelon, strawberries, meat, eggs, brazils, seafood, and sunflower seeds. 
The herbs bilberry and gingko also help. And see [9].

GLAUCOMA
All sites seem to agree that regular mild exercise is important to prevent glaucoma, and so is diet, see above. Smoking, caffeine and white sugar are out again, I’m afraid. For details see [10].

And here are some suggestions of natural remedies you can try for minor complaints.

EYE INFECTION
There are various types of eye infections you can get: blepharitis, styes, red eye/conjunctivitis, pink eye, dry eyes etc. For useful sites, see [11].

FLOATERS 
Keep your eyes in constant movement. Roll your eyes upwards, downwards, sideways and in circular motions for a few minutes at regular intervals [12]. And, apparently, the brain ignores floaters faster if you gaze at the moon for just five minutes every night. Easily said ….
DRY EYES - see [13].
PUFFY EYES - see [14].
YELLOW EYES - see [15].
RED/PINK EYES/CONJUNCTIVITIS - see [16].
UNDER EYE BAGS - see [17].
EYESTRAIN - see [18].
STYES - see [19].
COMPUTER VISION - see [20].
TWITCH - see [21].

And did you know that rubbing your eyes is bad for them? Personally, when they itch, I massage the corners with saliva .... Just bathing them in cold water also helps [22].

RECIPES


PASTA DIFFERENT for 1 to ???
Lots of shredded greens like cabbage, (frozen) peas, pasta, easy-to-cook meat like mince, sausage or bacon; basil, (cream cheese), spices, seasoning.
Prepare the vegetables, and heat slightly salted water. When it boils, throw in the pasta and veg, which should take roughly the same time to cook. If the peas are frozen, add them a bit later. If you use sausages or bacon, cut in ab. 2.5cm pieces and fry.
When the veg-pasta mix is done, pour off the water (good for soup!) and add the mix to the frying meat. Stir; season; add basil and spice it up, chilli is good. Also, or instead of the meat, mix in some cream cheese if you like and make sure it melts.
Enjoy.

Heat the oil, add the first lot of ingredients and cook for 3 minutes until the onion is translucent. Then add the potatoes and cook for 2 more minutes. If the spices start to stick to the bottom, put in a tiny splash of water. Add the chickpeas, tomatoes, and the liquid. Simmer for 15 minutes or until the potatoes are cooked and the sauce has thickened. Adjust salt. Stir in the shallots and parsley. Serve with rice, or add just a little bit more potatoes for a full meal.

Cook the pasta al dente. Heat the oil, throw in the anchovies and sizzle for 2 minutes until they’ve broken down. Add garlic, chilli and oregano and cook for 1 minute. Pour in the tomatoes, increase the heat and bubble for 3-5 minutes or until the sauce has thickened. Stir in olives and capers. Drain the pasta, leaving a bit of water coating the strands, then tip into the sauce. Stir, add some olive oil and mix while heating it thoroughly. Serve straight away with fresh basil if you have any.

[7] In 2007 I was diagnosed with dry macular degeneration - the form which is supposedly incurable. The optician told me it was good to eat kale, which inspired me to do some more research. This is when I found that important nutrients to fight MD are lutein, vitamins C and E, beta carotene and zinc (and if you take lots of zinc you should take copper as well). 
Lutein, as well as many other nutrients, is abundantly in kale. In general, dark leafy greens and colorful fruits and vegetables are excellent. Kale and marigold tea have been my standby ever since. I bought blublocker glasses and still use them when watching the computer, the tv and 
in a car when faced with unpleasant headlights. Online you can get blueblockers to wrap around your prescription glasses from £40 at www.optimalowvision.co.uk. Click on anti-glare spectacles and make sure you choose one with blue-blocking filter. Or order ‘wraparound fitovers’ via Robert Frith (www.frithsopticians.co.uk) opticians in Devon or Somerset.
I managed to get rid of my macular degeneration entirely by these means, plus some acupuncture treatments. You might not be so lucky, but you certainly can do a lot yourself to prevent it getting worse.
